When wild marine mammals are captured they have to be taught how to eat dead fish. It goes against their nature – they are more predators than scavengers. And the quantities our whales consume are huge – if you try to bring on half a ton of live krill and small fish we are going to have questions.

Different whales feel different to touch – some are covered in barnacles and scars, whale lice and seaweed! But the normal skin feels incredibly smooth – I once read it described as a peeled hard-boiled egg – a description that made me laugh but is actually pretty accurate.
